Technograph TGI series

In addition to being used to measure the elasticity, proof stress and strength of materials, such as metals and plastics, these machines also help evaluate the quality of assembling in destructive tests and manufacturing processes of products.

< Multifunctional, Easy-to-Use Tensile and Compression Testing Machines >
Featuring indicators and switches integrated on their front operation panel, the machines have an easy-to-use design. The also make test control from a PC, data analyzing and data summarization possible, through using data processing software.
Use of High-Precision Load Cells and Control Systems Made in-house.
Using know-how in high-precision load cells and instrument digital indicator made in-house, Minebea produces feature-rich, easy-to-use systems with a better safety device.

Features

New Desk-Top testing mashine with high accuracy, high performance, and simple operation.
・High Accuracy
Accuracy of ±1 % (JIS Class 1) of the indicated value from 1/1 to 1/1000 of load cell capacity, accurac of ±0.5% (JIS Class 0.5) is available as an option.
Cross head speed range of 0.000 5 mm/min to 1 000mm/min (TGI-50kN to TGI-250kN : 0.000 5mm/min to 500mm/min).
Accuracy of cross head speed is ±0.1 % of speed setting over entire speed range.
・High performance with simple operatin.
Automatic load cell span adjustment, One-push auto zero, Auto return to test start position (No overshooting), Test condition registration, Manual 3 level speed setting (freely settable), Analog output of test force and position, and support for continuous repeated tensile and compression testing.
・Increased accuracy, with servo motor resolution four times greater than previous models. Position control is greatly improved, allowing steady operation in low speed ranges.
・Increased return speed
The return speed can be set as desired between 0.1 mm/min and 1500 mm/min (up to 10kN) and between 0.1 mm/min and 750mm/min (for 50kN and over).
